Application filed August 27, 1920.

To all whom 2'25 may concern:

Be it known that l, Gnonon Tr-rorrns Twmnr, a citizen of the UnitedStates, and a resident of Elizabeth City, in the county of Pasquotankand State of North Carolina, have invented certain new and usefullinprovements in Cutters for 'lransfer Rings, of which the following isa specification.

The present invention relates in general to knitting machines, and moreparticularly to cutting mechanism especially adapted for use with thetransfer mechanism of a knitting machine.

lderetofore in this art in the manufacture of certain articles requiringthe use of the transfer mechanism, it follows from the use of thetransfer mechanism that an undesirable edge of the material of thearticle placed upon the transfer is formed, and it is necessary toremove this edge before the article can be transferred. lhis has usuallybeen done by raveling down the undesirable edge. Such an operation iscostly in that it requires the expenditure of a very considerable timeand labor on the part of the transfer operatives.

The object of the invention is to provide for the expeditious andcomplete removal of this undesirable edge and to eliminate the necessityof the operatives raveling down the same; to provide a cutting mechanismfor carrying out this purpose which is so associated with the transfermechanism. as to in no way interfere with the placing of an articlethereupon and at the same time to be always effective to cleanly andcompletely remove the undesirable edge in a minimum time, and which isof simple and durable construction and easy and inexpensive tomanufacture.

Other objects and advantages of the invention reside in certain novelfeatures of construction combination and arrangement of parts as will behereinafter more fully described and particularly pointed out in theappended claims, reference being had to the accompanying drawingsforming part of this specification, and in which:

Figure 1 is a side clevational view of the transfer mechanism, theassociated cutting mechanism being shown in perspective;

Figure 2 is a bottom plan View of the transfer mechanism and cuttingmechanism;

Figure 3 is a transverse vertical sectional View, on line 3-3 of Figure2; and

Specification of Letters Patent.

Patented Jan. 3, 1922.

Serial No. 406,345.

rlgures 4 and 5 are detail perspective views of the cutting mechanismdetached from the transfer.

Referring to the drawings, it will be seen the invention contemplates atransfer mechanism of conventional construction which as usual includesa transfer cup 0 having an integral lug c from which the pin 1) depends.The pin p is adapted to be received in a socket 8 provided in thebracket S which is secured to any suitable support. A transfer ring 1having quills 2f as usual is rotatably received in the transfer cup U.As is well known in the art, the quills t are adapted to receive thefabric of the article being manufactured and the undesirable edge whichit is desired to remove extends exteriorly from the quills and lyingupon the outside surface of the transfer ring T.

The cutting mechanism for removing this undesirable edge is designatedgenerally at M. The cutting mechanism includes a base 10 which isprovided with a slot 11 which extends from the outer end of the base andcentrally thereof for a greater portion of Its length. The base 10 ofthe cutting mechanism is adapted to be disposed against the under sideof the transfer cup C and is adjustably secured thereto, preferably bymeans of a bolt 12, the shank of which extends through the slot 11 ofthe base 10 and is then threaded into the transfer cup. A washer 13 isinterposed between the head of the bolt 12 and the base 10 to moresecurely fasten the base in adjusted position. A body portion lel isformed integral with the base 10 and extends upwardly and inwardly overthe base 10, so that when the cutting mechanism is associated with thetransfer mechanism the body portion 14: extends upwardly and inwardlyover the transfer cup and the transfer proper, the transfer cup C beingcut away slightly for this purpose, as shown at 20 in Figure 3. A cutter15 which has a highly sharpened knife edge 15 is secured, as at 16, tothe upper end 146 of the body portion 14. The upper end 14 of the bodyportion is curved backwardly from the incline of the body portion 1% soas to extend substantially vertically. The securing means 16 for thecutter proper includes a holder or clamp plate 16 and a set screw 16which extends through the holder plate and is seated in the end 14* ofthe body portion.

Adjacent the knife or cutter 15 the body portion 14' is cut away, as at17, and this forms a beveled table 18, upon which the edge is receivedas it is fed to the knife. A discharge opening 19 for the cuttings isalso formed.

In practice, it will be noticed that the cutting mechanism is firstadjusted to the sary to gr the edge and pull on the same across the tale 18 and past the cutter. The cutter "severs the edge from theremainder of the fabric on the transfer, the transfer ring rotating toaccommodate a complete removal of the edge. This operation may becarriedout very ra idly as a simple grasping and pull is a1 at isnecessary to cleanly and completely remove the edge.

I claim:

1. In 'a device of the character described, in combination, a transfermechanism including a cup and a transfer ring rotatably mounted in saidcup and adapted to carry a fabric having an edge overlying the exteriorthereof, cutting mechanism for re moving "the edge of the fabriccomprising a base provided with a slot, means for adjustably clampingthe base to the transfer cup including a bolt havin its shank extendingthrough the slot of said base and seated in the transfer cup and awasher interposed between the head of the bolt and the base, a bodyportion integral with the base and extending over the transfermechanism, said body portion being cut away at its upper end to providea beveled table and a discharge openin for the body portion, a cutterhaving a Iiighly shar ened knife edge arran ed adjacent said tab e,means for clamping t e cutter to the body portion includin a clampingplate, and a set screw, where y when the edge is grasped and 2. In adevice of the character described,

in combination, a transfer mechanism including a cup and a transfer ringrotatably mounted in said cup and adapted to carry a fabric having anedge overlying the exterior thereof, cutting mechanism for removing theedge of the fabric comprising, a base, a body portion integral with thebase and extending over the transfer mechanism, said body portion beingcut away at its upper end to provide a beveled table and a dischargeopening for the body portion, a cutter having a highly sharpened knifeedge arranged adjacent said table, whereby when the edge is grasped anddrawn across the table it will be severed from the remainder of thefabric on the transfer ring.

3. In a device of the character described, in combination with atransfer mechanism including a cup and a transfer ring rotatably mountedtherein, cutting mechanism including a base adjustably secured to thetransfer cup, a body portion extending from said base over the transfermechanism, and a cutter secured to the upper end of the body portion anddisposed closely adjacent said transfer ring.

4. In combination with transfer mechanism including a cup and arotatable transfer rin in said cup, cutting mechanism carried by the cupand cooperably arranged with respect to the transfer ring for removingthe edge of the fabric carried by the transfer mechanism upon rotationof the transfer ring.

5. In combination with a rotatable transfer ring, cutting mechanismincluding a cutter cooperably arranged with respect to the transfer ringand adapted to remove the edge of the fabric carried b the transfer ringwhen the edge of the fa ric is grasped and drawn across the cutter, therotatable transfer ring partaking of rotary motion to accommodate thisaction.
